Abstract

L'invention concerne un procédé de fixation d'un palier (7) sur une turbomachine comportant un stator et un rotor, le palier (7) comportant :. une première partie (73) fixée sur le stator de la turbomachine au moyen d'une pluralité de vis (80) et d'écrous (85),. une seconde partie (74) fixée sur le rotor, mobile en rotation selon un sens de rotation donné, et. un roulement (70) disposé entre les première (73) et seconde (74) parties du palier.Le problème que se propose de résoudre l'invention est d'améliorer la fixation du palier (7) en la rendant plus fiable et plus robuste, en particulier contre le dévissage. Pour résoudre ce problème, le procédé consiste à utiliser des vis (80) ayant un sens de rotation de vissage contraire au sens de rotation du rotor.
